Detailed Description

A path that can be drawn to a canvas.

Member Function Documentation

def __init__ (   self,

Construct a new instance of a Path.

The path is described as a series of points that are connected in order.

These points can be initialized by sending each individual Point
as a separate parameter, or by sending a single parameter
containing a sequence of Points. If no parameters are sent, the
path initially has zero points.

The reference point for a path is initially aligned with the first
point of the path.

Reimplemented from Shape.

Reimplemented in Polygon.

def addHandler (   self,
) [inherited]

Register an EventHandler instance with this object.

def addPoint (   self,
  index = -1 

Add a new point to the Path.

point  a Point instance
index  designates where on the path the new point is placed
   (at the end, by default)

def adjustReference (   self,
) [inherited]

Move the local reference point relative to its current position.

Note that the object is not moved at all.

def clearPoints (   self  ) 

Remove all points, setting this back to an empty Path.

def clone (   self  )  [inherited]

Return a duplicate of the drawable object.

Note that the duplicate is not automatically added to any
canvases or layers, even if original is currently so.

def deletePoint (   self,
  index = -1 

Remove the Point at the given index.

By default, deletes the last point.

def flip (   self,
  angle = 0 
) [inherited]

Flip the object reflected about its current reference point.

By default the flip is a left-to-right flip with a vertical axis of symmetry.

angle     a clockwise rotation of the axis of symmetry away from vertical

def getBorderColor (   self  )  [inherited]

Return the color of the object's border.

def getBorderWidth (   self  )  [inherited]

Return the width of the border.

def getDepth (   self  )  [inherited]

Return the depth of the object.

def getNumberOfPoints (   self  ) 

Return the current number of points.

def getPoint (   self,

Return a copy of the Point at the given index.

Subsequently mutating that copy has no effect on the Path.

def getPoints (   self  ) 

Return a list of Point instances that are copies of the points on the Path.

def getReferencePoint (   self  )  [inherited]

Return a copy of the current reference point.

Note that mutating that copy has no effect on the Drawable object.

def move (   self,
) [inherited]

Move the object dx units along X-axis and dy units along Y-axis.

For the default coordinate system, positive dx is rightward and
negative is leftward; positive dy is downard and negative is upward.

def moveTo (   self,
) [inherited]

Move the object to align its reference point with (x,y)

def removeHandler (   self,
) [inherited]

Unregister an EventHandler instance from this object.

def rotate (   self,
) [inherited]

Rotate the object around its current reference point.

angle  number of degrees of clockwise rotation

Reimplemented in Text.

def scale (   self,
) [inherited]

Scale the object relative to its current reference point.

factor      scale is multiplied by this number (must be positive)

Reimplemented in Text.

def setBorderColor (   self,
) [inherited]

Set the border color to a copy of the indicated color.

The parameter can be either:
   - a string with the name of the color
   - an (r,g,b) tuple
   - an existing Color instance

def setBorderWidth (   self,
) [inherited]

Set the width of the border to the indicated width.

Reimplemented in Button.

def setDepth (   self,
) [inherited]

Set the depth of the object.

Objects with a higher depth will be rendered behind those with lower depths.

def setPoint (   self,
  index = -1 

Change the Point at the given index to a new value.

By default, the last point is changed.

def shear (   self,
  angle = 0 
) [inherited]

Shear the object relative to its current reference point.

By default, points with the same y-coordinate as the reference point are left
unchanged.  A point d units above the reference point is shifted d * shear
units to the right.  The optional angle parameter rotates the axis
that the shearing occurs along.

angle      clockwise angle for shear

def stretch (   self,
  angle = 0 
) [inherited]

Stretch the shape in mutltiple direction.

By default the x-axis is scaled by a factor of xFactor and the
y-axis is scaled by a factor of yFactor.  The optional
parameter rotates the directions that the streching is performed

def wait (   self  )  [inherited]

Wait for an event to occur.

When an event occurs, an Event instance is returned
with information about what has happened.
